How to put icons in...browsing

I'm new to Python and to Pythonista. I'm working on a program that fetches data and put the results in a view. I made a design in the UI Editor, it consists labels for textual results and Image Views for icons.

My problem is to put icons in the Image Views. I have a map consisting gifs. An ImageView icon points to the IOS images like alert_24 (the !). Can I redirect it to my map of gifs?

To put text in a label I use: v['label1'].text = placeDate
Can I do something similar to put icon therm.gif in imageview9?

As the .Gif file contains the duration of each frame, my little script has been modified because the duration parameter is not needed.
Name of class and view parameter are also modified because the view in which the gif will be displayed may be any View, not only an ImageView.
I also remove the touch_ended method because it is not needed here.
Sorry for these modifications, I had posted too quickly, just to be sure I'd not forget, I've a so bad memory 😢

Here the same result with your code for the imageview. When I bypass GifInView and load a png in my pyui with r['imageview1'].image = ui.Image.named('./gif/image.png'), the picture fills the whole frame.
